3D HYDRO ENVIRONMENTAL MODEL OF DISSOLVED OXYGEN DISTRIBUTION IN YANGTZE ESTUARY

摘要：

By application of hydro environmental model EFDC in Yangtze Estuary, temporal and spatial variation of dissolved oxygen demand (DO) distribution was obtained by setting up a 3D water quality calculation. Also field observation data were available and compared with the numerical results.Referred to figure 1 and figure 2, it is concluded: the concentration of DO in north branch is much higher than in south branch due to consumption of oxygen in south branch by sewage discharge from Shanghai;The concentration of surface is larger than that of bottom layer; there is a low concentration area below 20m contour line, and high concentration between 20m and 30m contour line; it also prove the EFDC model is of satisfactory accuracy in water quality modeling of Yangtze Estuary.
